I'm trying to get the serial number of Samsung tablets. If I go to Settings > About device > Status the serial number shown is 00000000000. If I do the same thing on another Samsung device a different (probably correct one) serial number is shown.
In my app by using Build.SERIAL I can see that a serial number, different from 00000000000 is given. But if I use ril.serialnumber, again 00000000000 is shown. Can you explain me why does this happen and what does it mean if my serial number is 00000000000? Thanks!
